TRANSOM-OPERATING MEANS.

Specification of Letters Patent.

Patented Nov. 23, 1915.

Original application filed March 13, 1913, Serial No. 753,953. 7 Divided and this application filedrcbrumy 12, 191%. Serial No. 818,190.

. To all whom it may concern:

Be it known that 1, Louis B. SMYSER, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and use ful Improvements in Transom-Operating Means, of which the following is a full, clear, and exact description.

The present invention relates to an improved form of operating means for tran-' soms and other swinging closures, and constitutes a division'of my pending application Serial No. 753,953.

The invention is described in detail in the following specification taken in connection with the accompanying drawings forming part thereof, and illustrating a preferable embodiment of the invention.

In these drawings: Figure 1 is a frag.- mentary view in elevationof the inner'face of a supporting wall having the operating gearing of the present invention applied thereto. Fig. 2 is an end elevation, partly in section, of the parts 1 shown in Fig- 1. Fig. 3 is a view in elevation of the operating gearing, the gear case being broken away and. partly in section to disclose the interior arrangement. Fig. 1 is a horizontal sectional view through a door casing illustrating the concealed nature of the gear case and the position of the supporting plate and gear casing within the door casing. Figs. 5 and 6 are views of an enlarged scale of details of the gearing. Fig. 7 isa view in side elevation showing the application of my operating means to a transom controlling device of the type shown in my copending application aforesaid.

The operating mechanism. of the present invention is especially designed for use in connection with transom operators of the concealed type, or that type wherein the operating mechanism is concealed for the most part within the door casing, although, of course, the operating means per 86, may

, be used in connection with exposed types of operators. 1 am, however, dlsclosing the mechanism as used in connection with one specific form of transom controll ng means,

In the drawings, 1 designates a supporting plate or frame attached to the inner face of a supporting wall 2, which in the present instance, constitutes the door ca sing. Extending vertically of the door casing on its inner side, is a bar 3 designed to be operatively connected adjacent its up per end with suitable transom controller mechanism. The particular form of controlling means per se for the transom is immaterial, however, theinvention concerning the construction of gear casing and operating gearing as Well as other features here: inafter pointed out. In order to move this operating bar 3, its lower end is formed as arack El; and a gear casing 5 is provided through which this rack end of the bar is guided, this gear case being secured to the frame 1 by means of stove bolts 6 which extend through apertures formed in the plate 1 and through bores formed in the "door ja nb. 2, and serve also to connect the lower end of'the plate ltothe .jamb. These bolts extend out of and are accessible from the door side of the jamb, as will be clearly seen from the drawings. The gear casing is pro vided with a cover 7 including gear housings 8 and 9. A rack-engaging gear wheel 10 is seated in the base of the gear casing and is provided with an integral sleevell and with bosses 12 formed at opposite ends of this sleeve and gear wheel by means of which this gear element is journaled in the gear case. The sleeve portion 11 of this gear element, intermediate its ends, is formed with an annular worm gear 18 thereon, and is also provided with a central bore 1 1 having afby-pass connection 15 with this annular gear 13 for the purpose of transmitting a lubricant thereto, as will be more clearly apparent hereafter. Extending through the gear housing 9 and transversely ofthe, housing 7 is a bolt 16 having itshead seated in a recess formed in the side of thehousing and having a threaded end threaded in the 45 V I ture 25 of the hub 24, is centrally positioned positioned in the lower portion of the housing 9.

The gear housing 9 is separate from the housing 8 and cover 7 of the gear casing and is held thereto by means of the bolt 16 and by the provision of an outward offset 21 in the cover 7, which offset part is provided with a toothed upper edge engaging with the toothed lower edge 22 of the housing 9. NVithin theupper portion of the housing 9 is journaled a second gear wheel 23 in mesh with the gear 20 in the lower portion of thecasing, this gear 23 being suitably journaled within the housing 9 and having a hub 24 extending through a bore in the casing 9 and provided with a squared aperture 25 therein.

Referring specifically to Fig. 4 of the drawings, it will be seen that the frame 1 is mounted upon the inside of the door jamb and that the gear case and its housings rest against the adjacent buck 26 which may be recessed to receive these gear housings. The space between the buck and j amb is, of course, covered by the usual strip of trim or molding 27. This space makes the door frame in effect a hollow wall or partition, upon an inside face of which the transom operating parts are mounted. It is through the gear 23 that motion is transmitted to the rack-engaging gear wheel andthrough the rack of the operating bar to the transom.

The appearance of the attachment is im- V the offset 21.

proved if the operating handle, hereinafter described, which engages the squared aperwith reference to the molding 27. This is possible by reason of the fact that the housing 9 may be swung upon the bolt 18 as a pivot to position its hub 21 at the desired point, the bolt being first unscrewed and the housing pulled out sufficiently to clear its toothed edge 22 from the toothed edge of When the hub 24. has been properlypositioned relatively to the molding 27, the housing 9 is pushed into engage its toothed edge 22 with the teeth of'the offset 21, and the bolt 18 when screwed in and its nut tightened. It is further desirable to providemeans for lubricating the parts of the gearing which are not easily accessible. In the specific form of gearing disclosed herein, such parts will be particularly the gear elements 1.9 and 13, the lubricant being distributed from these elements to the other gear elements. To this end I provide a bore in the door jamb 2 in alinement with the boss 12'of gear 10 through which boss, gear and its sleeve 7 the lubricating aperture 14; extends, and insert into said bore in the boss 12,: an oiling tube. 28 to the outer end of whichis secured a valve casing29 having in its outer end a lubricant inlet opening v30 normally closed by a ball valve 31 pressed thereagainst by a coiled spring 32. The outer end of this valve inlet to the lubricating tube is positioned at the door side of the j amb 2, preferably slightly within the edge of the jamb so that access may be readily had thereto for the purposes of lubricating the gearing. The lubricant will pass through tube 28, bore 14 and by-pass 15 to the worm gearing 1319 and thence be distributed to gears 102023 by rotation and centrifugal action.

The molding strip 27 is, of course, provided with a suitably located bore through which the spindle 33 of an operating handle 34 extends, a suitable rose 35 being preferably provided and resting against the outer face of the molding 27. The inner end of: the spindle 33 is squared and seatsin .the

squared socket 25 of the hub of gear 23 so that when the handle is turned from the exterior, the worm gearing 13l9 operated through gear train 23-20, operating the rack and pinion gearing i10 to raise or lower the operating bar 3. All of the operating parts, except the operating handle 34 and'rose 35, are concealed from View so that the appearance of the door or other casing is not marred.

WVhile I have herein described andjillus trated a specific embodiment of my inven-- tion, it should be understood that the same may be altered in detail and relative arrangement of parts within the spirit of the invention and the scope of the appended able on said support to maintain said axes substantially parallel atdiiferent positions of adjustment to preserve said driving connection.
